摘要
Poly (ethylene axide) (PEO) modified WO 3 thin films were prepared on glass substrates with special temperature.The sol gel transition proess was investigated by using DTA-TG,SEM and XRD.The electrochemical characteristic of the films was studied by cyclic voltmmetry measurement.The results show that PEO has heavy effects on the crystallization of WO 3 during structure evolution because of the interaction between PEO and WO 3.It increases the crystallization temperature of the gels and thus improves the electrochemical properties and cyclic life of WO 3 film as electrochromic materials.
